[0054] Figures 1 to 3 This is the first embodiment of the present invention. (As shown...) Figures 1 to 3As shown, the acid and alkali resistant flooring unit 100 of the present invention includes: a support plate 1, which is a square plate; a bottom support structure 2, which is disposed at the bottom of the support plate 1; and an acid and alkali resistant coating 3, which is attached to part or all of the surface of the support plate 1 and / or the bottom support structure 2. Through this structure, the purposes of convenient manufacturing and acid and alkali resistance can be achieved. It will be described in detail below.

[0055] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the disclosure of this specification.

[0056] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate their understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives of the invention, should still fall within the scope of its technical content. Furthermore, the terms "upper," "lower," "left," "right," and "one" used in this specification are merely for ease of description and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, are also considered within the scope of the invention's implementation.

[0057] In this specification, "first to fourth embodiments" refer to various structural variations of the support plate and bottom support structure, while "embodiments 1 to 3" refer to various compositional variations of the acid and alkali resistant coating. Furthermore, to facilitate understanding of features such as the acid and alkali resistant coating 3, some features in the illustrations have been exaggerated or enlarged, and the dimensions and proportions of the constituent elements may not be identical to the actual dimensions.

[0058] like Figures 1 to 3 As shown, the support plate 1 is a square plate, and its structure can have various variations. For example, it can be constructed as a floor unit 100 by using a structure without ventilation holes and integrally forming it with the bottom support structure 2. The floor unit 100 can be called a blind plate and has high strength. Figures 4 to 6 These are the second to fourth embodiments of the present invention. For example... Figure 4 As shown, the support plate 1a adopts a structure with many circular ventilation holes 11a to form a floor unit 100a integrally molded with the bottom support structure. This floor unit 100a can be called a honeycomb board and has a ventilation effect. Figure 5 As shown, the support plate 1b adopts a structure with many elongated ventilation holes 11b to form a floor unit 100b integrally molded with the bottom support structure. This floor unit 100b can be referred to as a grating plate and has a ventilation effect. Figure 6As shown, the support plate 1c adopts a structure with at least one window 12c to form a floor unit 100c integrally molded with the bottom support structure. This floor unit 100c can be referred to as a window plate, facilitating observation of the space beneath the floor. Furthermore, each window 12c on the support plate 1c is equipped with a matching transparent cover plate 13c, which can be made of acrylic or tempered glass. After the acid and alkali resistant coating 3 is applied, the transparent cover plate 13c is installed on the window 12c of the support plate 1c.

[0059] like Figure 2 As shown, the bottom support structure 2 is located at the bottom of the support plate 1 to reinforce the support plate 1. It may include: four side frames 21 surrounding the bottom of the support plate 1; and a number of auxiliary ribs 22 arranged in a crisscross pattern within the four side frames.

[0060] The acid and alkali resistant coating 3 is applied to part or all of the surface of the support plate 1 and / or the bottom support structure 2. The area where the acid and alkali resistant coating 3 is applied can vary depending on the usage requirements, as illustrated below. Taking a raised floor with blind panels as an example, the environment in the upper and lower spaces of the raised floor may be different, and the top of the blind panel can be covered with tiles of various effects. Therefore, the top of the blind panel does not require an acid and alkali resistant coating; the coating can only be applied to the bottom surface of the support plate and all surfaces of the bottom support structure. If the top of the blind panel is not covered with tiles, then the acid and alkali resistant coating must be applied to all surfaces of the support plate and the bottom support structure. Taking a raised floor with honeycomb panels as an example, the top of the honeycomb panels can be covered with tiles of various effects. Therefore, the top of the honeycomb panels does not require an acid and alkali resistant coating; the coating can only be applied to the bottom surface of the support plate and all surfaces of the bottom support structure. If the top of the honeycomb panels is not covered with tiles, then the acid and alkali resistant coating must be applied to all surfaces of the support plate and the bottom support structure. Taking a raised floor with grating panels as an example, air passes directly through the floor units, and the environments in the upper and lower spaces of the raised floor are relatively similar. Therefore, the acid and alkali resistant coating can adhere to the entire surface of the support plate and the bottom support structure. Taking a raised floor with blind panels as another example, sometimes acidic or alkaline droplets may occur when equipment is operating on the raised floor. Therefore, the acid and alkali resistant coating can adhere to the top surface of the support plate to prevent surface dents, bubbles, particles, expansion, cracking, and peeling.

[0061] The characteristics of the acid and alkali resistant coatings will be described in detail below using Examples 1 to 3. The composition of the acid and alkali resistant coatings in Examples 1 to 3 may vary depending on requirements, containing different weight percentages. The additives include leveling agents, brightening agents, and / or matting agents, while the pigments and fillers include silver, titanium dioxide, ultramarine, red, and / or yellow. However, Examples 1 to 3 of the acid and alkali resistant coatings are provided for illustrative purposes only and should not be construed as limiting the scope of the invention. All modifications and designs made in accordance with the listed claims should be included within the scope of this invention.

[0062] Example 1: The acid and alkali resistant coating comprises 32% epoxy resin, 32% polyester resin, 5% additives, 29.4% pigments and fillers, and 1.6% silver powder by weight, with an average particle size of 30 to 90 micrometers. Example 1 is a silver-gray powder coating. The solid acid and alkali resistant coating formed in Example 1 has a hardness of H-2H, and under the cross-cut adhesion test, it is 100% intact without peeling, dents, bubbles, particles, or changes in resistivity. Furthermore, under tests of 5% acid (sulfuric acid prepared with deionized water to a 5W / V sulfuric acid solution), alkali (anhydrous sodium carbonate prepared with deionized water to a 5W / V alkali solution), and salt (sodium chloride prepared with deionized water to a 5W / V salt solution), the primer film showed no abnormalities after 24 hours at room temperature, and the surface silver powder showed reduced discoloration. Furthermore, the solid acid and alkali resistant coating formed in Example 1 showed no discoloration after 24 hours of testing in tin plating solution, copper plating solution, and nickel plating solution, and exhibited no abnormalities in the cross-cut adhesion test. This example does not contain curing agents or conductive agents; the silver powder may be used to increase surface gloss.

[0063] Example 2, the acid and alkali resistant coating comprises 62.3% epoxy resin, 3.1% curing agent, 3.5% additives, 25.4% pigments and fillers, and 5.7% conductive agent by weight, with an average particle size of 30 to 90 micrometers. Example 2 is a gray conductive powder coating. The solid acid and alkali resistant coating formed in Example 2 has a hardness of H-2H, is 100% intact without peeling under cross-cut adhesion testing, and has a resistance of 1 at 100V. Below 108 ohms, there are no depressions, bubbles, or particles. Furthermore, the solid acid and alkali resistant coating formed in Example 2 showed no abnormalities in the primer film after 120 hours at room temperature under a 5% acid, alkali, and salt resistance test.

[0064] Example 3, the acid and alkali resistant coating comprises 62.7% epoxy resin, 3.1% curing agent, 3.5% additives, 25% pigments and fillers, 3% conductive agent, and 2.7% silver powder by weight, with an average particle size of 30 to 90 micrometers. Example 3 is a silver-gray conductive powder coating. The solid acid and alkali resistant coating formed in Example 3 has a hardness of H-2H, is 100% intact without peeling under cross-cut adhesion testing, and has a resistance of 1 at 500V. Below 106 ohms, there are no dents, bubbles, or particles. Furthermore, the solid acid and alkali resistant coating formed in Example 3 showed no abnormalities in the primer film after 72 hours at room temperature under 5% acid, alkali, and salt resistance tests, and the surface silver powder showed reduced discoloration.

[0065] Figures 7 to 8 The diagram shows a processing apparatus 400 for an acid and alkali resistant flooring unit, used to process and manufacture the aforementioned acid and alkali resistant flooring unit 100. (As shown...) Figures 1 to 8 As shown, the processing apparatus 400 for the acid and alkali resistant floor unit of the present invention includes: a suspended conveying device 4 having a track 41 and a plurality of suspension frames 42, the suspension frames 42 being used to suspend an acid and alkali resistant floor unit 100; a loading area 5, a spraying chamber 6, a baking chamber 7, a cooling area 8, and a unloading area 9 are sequentially arranged around the track 41 of the suspended conveying device 4; the spraying chamber 6 has at least one spraying window 61, allowing an operator to spray powder coating onto a predetermined position of the acid and alkali resistant floor unit 100; the predetermined temperature in the baking chamber 7 allows the powder coating on the acid and alkali resistant floor unit to be sintered; through this structure, the coating operation of the acid and alkali resistant floor unit can be conveniently carried out, achieving the purpose of conveniently manufacturing the acid and alkali resistant floor unit.

[0066] The track 41 of the suspended conveyor 4 can be a circulating track for convenient continuous operation.

[0067] The loading area 5 allows operators to suspend the acid and alkali resistant flooring units 100 on the suspension bracket 42. Before loading, pre-treatment such as sanding the rough edges can be performed.

[0068] The spray booth 6 has at least one spray window 61 for operators to spray powder coatings onto predetermined locations of the acid and alkali resistant floor unit 100. When it is necessary for the acid and alkali resistant coating 3 to adhere to all surfaces of the support plate 1 and the bottom support structure 2, the spray booth 6 may have two or more spray windows 61 (not shown). In addition, a powder coating recovery device (not shown) may be installed within the spray booth 6 to recover the powder coating and prevent its spread and environmental impact. The powder coating recovery device may have functions such as suction, filtration, and powder coating collection; these are conventional technologies and will not be described in detail here.

[0069] The predetermined temperature in the baking chamber 7 can sinter the powder coating on the acid and alkali resistant floor unit. Taking the composition of the acid and alkali resistant coating used in Examples 1 to 3 as an example, the predetermined temperature in the baking chamber 7 is 200 to 240 degrees Celsius, which can form an acid and alkali resistant coating with good adhesion and hardness.

[0070] Cooling zone 8 is used to cool the product of the powder coating melting to form a solid acid and alkali resistant coating 3. The cooling method is not limited; for example, the acid and alkali resistant floor unit that has left the baking chamber 7 can be continuously hung on the suspension rack 42 and cooled by natural air cooling or forced air cooling.

[0071] The lower section 9 allows the operator to remove the acid and alkali resistant floor unit 100.

[0072] See again Figure 8 Between the loading area 5 and the spraying chamber 6, a cleaning area 51 and a drying area 52 can also be provided. Before spraying the powder coating, 1. the cleaning area is used to clean foreign objects such as dust and grease on the acid and alkali resistant floor unit 100, and 2. the drying area is used to dry the acid and alkali resistant floor unit 100 to increase its adhesion.

[0073] like Figure 9 As shown, the present invention further provides a processing method for an acid and alkali resistant floor unit, which, after cleaning and drying the acid and alkali resistant floor unit 100, further includes the following steps: 1. suspending an acid and alkali resistant floor unit on a suspended conveying device; 2. spraying a powder coating onto a predetermined position of the acid and alkali resistant floor unit; 3. baking the acid and alkali resistant floor unit at a predetermined temperature, so that the powder coating is sintered to form an acid and alkali resistant coating adhering to the surface of the acid and alkali resistant floor unit; and 4. removing the acid and alkali resistant floor unit after it has cooled.

[0074] Suspending an acid-alkali resistant floor unit on a suspended conveyor facilitates subsequent powder coating application, particularly allowing for the application of separate coatings to the entire surface of the top and bottom support structures of the acid-alkali resistant floor unit. Furthermore, where appropriate, such as when only the top surface of the acid-alkali resistant floor unit needs to be coated, it can be transported via a conveyor belt (not shown in the figures). Additionally, taking the composition of the acid-alkali resistant coating used in Examples 1 to 3 as an example, when baking the acid-alkali resistant floor unit at a predetermined temperature, the predetermined temperature can be 200 to 240 degrees Celsius.

[0075] The above are embodiments of the present invention, provided only to illustrate the principles and effects of the invention, and should not be construed as limiting the scope of the invention. Any person skilled in the art can modify the above embodiments without departing from the spirit and scope of the invention.
